Hi @razvan_iacob,
Did you just paste the output twice by mistake or do you really have duplicate sections in the INI file?
Also, try to redploy with:
# php $BASE_DIR/app/deployment/uiconf/deploy_v2.php --ini=/opt/kaltura/apps/studio/v2.0.8/studio.ini
or, if running on Ubuntu/Debian, the same as above but adding --user=www-data and then also reload Apache.
and remember to reload Apache afterwards.
